Croatia "tricked us in a way" when it signed a memorandum halting court procedures against the defunct Slovenian bank Ljubljanska Banka (LB) and its successor, Nova Ljubljanska Banka (NLB), the largest bank in Slovenia.

Under the agreement signed in March 2013, all legal actions against LB bank and NLB will stay until a solution is found, Erjavec told local mass media.

However, "Croatia is interpreting things its own way now."

The Zagreb Municipal Court ruled in January that the defunct LB bank and NLB must compensate two Croatian banks, Zagrebacka banka and Privredna banka Zagreb (PBZ), which sued on behalf of the government of Croatia for LB deposits that had been guaranteed and paid by Croatia through the two banks.

The total amount of compensation approaches 27 million euros (36.7 million U.S. dollars).

Apart from their bank dispute, Slovenia and Croatia also have been in dispute over sovereignty of the northern Adriatic bay of Piran.

In November 2009, Slovenia and Croatia signed an agreement in Stockholm, Sweden, agreeing to resolve their maritime border dispute through the Hague-based international arbitration tribunal.

Slovenia sent its official memorandum over the border dispute with Croatia to the Hague-based international arbitration tribunal in November 2013.

Slovenia is well prepared for the border arbitration procedure, Erjavec said.

The tribunal was reportedly to make a decision over the border dispute in 2015.

To overcome the two problems with Croatia have been Slovenia's "top priority" in terms of bilateral relations with neighbouring countries, Slovenian Press Agency said.

Both Slovenia and Croatia declared independence from former Yugoslavia in 1991.
